swarm DRIVER AND. Ex'rmc'roa.

To all wlwm it may concern:

Be it known that I, JOHN K. BIGELOW, a

Oakland, in the county of Alameda and State of California, haveinvented new and useful Improvements in Staple Drivers and Extractors, of which the following isa specification.

The objectof the present invention-is to provide a convenient instrument for driving staples, espegially those used in wire'fencing, for. extracting the staples, and for stretching wire.

I11 the accom anying drawing, Fi re 1 is a. side View 0 the sta le driver; Fig. 2 is lit angles from Fig. 1, partly in section; Fig. 3 is across section; Fig. 4 is a broken side-view showing the de vice used as anextractor; Fig. 5 is an en-' larged longitudinal section the handle being partly broken away; Fig. 6 is a side view of the extractor hook; Fi 7 is a transverse section of the same; Fig. 8 is an end .view of the device shown in Fig. 4, R'eferringto the drawing, my improved a cylindrical steel bar 1, one end of which has preferably a'bev eled edge 2. The other end is formed'with a central recess 3, havin two diametrically opposite extensions or'en argements 4,adapted to receive the sides of a sta'ple,shown at at its recessed end, in a plane at right angles to the plane through said extensions, isformed an elon- 6, through which-extends a free end of a wire spring 7, which spring extends longitudinally on the side of the minal portion being bent at right angles, passed through a hole 8 in the bar and The free end of the "spring is bent back upon function of which is to-extend inward to" a position. behind, or outside of, the central or cross portion of the staple when in position, as shown in Fig.2, and thereby retain the same in the bar or driver -1'. v

In use the staple is inserted in the recess 3fin the driver,

the staple presses outward the bentend of the spring and then passes the same, said so that the middle portion of bent end then springing back into place andretaining the staple in position. The sta le thus held in the end of the driver is applled to the fence post where it is desired to insert and, the driver being pressed toward the post so as to hold the staple in with a hammer u on the end of the driver, which has the e ect of driving the staple into the wood. The driver is then withdrawn from the staple, the force of the spring 7 being very small and insuflicient to offer any considerable resistance to the withdrawal of the driver. r I

My improved instrument can also be used as a staple extractor. For this purpose'I provide the device shown said device consisting of a plate, 10 formed at one end into a hook or jpolnt 11 and at the other end having a longitudinal recess 12, made by stamping oi pressing the metal laterally when forming the extractor, so that the outer face of the metal, opposite to in detail in Fig. 4, I

saidgroove, extends beyond the corresponding face of the main portion of the extractor. This groove is adapted to receive the nose 9 of the spring Tin the bar so that said spring retains the extractor in positionin the body of the instrument. The use of the extractor is obvious. The pointedend of the same is inserted beneath the staple, and the extractor and' the bar secured thereto are then used as a lever to withdraw the sta le. The plate,10 is preferably formed which prevents the same soft wood, I claim i A holder 'for a staple or'staple extractor sinking deeply into comprising a bar formed at one end to receive the blowof a hammer andihaving in the other end a recess elongated in cross section, said end having an aperture extending from the side of the bar'into said recess in adirection transverse to. the direction of elongation ofsaid recess, and a spring wit -a widened rear edge as shown at 16, I
